Description

2, the 2- dimethylthiazoles alkyl compound and its preparation method and purposes of substitution
Technical field
The present invention relates to a kind of novel substituted 2,2- dimethylthiazole alkyl compounds, its preparation method and its Protect hematopoiesis, immune system, the purposes in radiation protection.
Background technology
Ionising radiation (X or gamma-rays, the neutron and α particles with enough energy) makes biological tissue generate activity freely Base, these free radicals and critical macromolecular such as DNA, protein or biological membrane interaction, cause cellular damage or even can It can cause cell dysfunction and apoptosis.In recent years, with the anxiety of world's nuclear safety situation and the rapid hair of radiotherapy After nuclear leakage accident occurs for exhibition, especially Fukushima, Japan nuclear power station, the research of radioprotectant causes the concern of people again. Disease incidence or the death rate caused by can effectively reducing ionising radiation using radioprotectant.At present, clinically for spoke It is more to penetrate the drug of protection, mainly there is sulfur-containing compound, estrogen, cytokine class etc., but has certain side effect mostly, And druggability is poor, administration is inconvenient.
In order to overcome the shortcomings of more than drug, we, which design, has synthesized a series of 2,2- dimethylthiazoles alkyl compounds, And radiation protection biological value and protection hematopoiesis, the experiment of immune system are carried out to it.
The content of the invention

Wherein R can be C1-C6Straight chain and the preferred pi-allyl of the undersaturated alkyl substituent of branch, isopentene group, butyl- 2- Alkenyl or aromatic radical or the preferred benzyl of substituted aromatic group and the benzyl of substitution, can also be C1-C6Straight chain and branch Chain carbonyl substituent group, wherein the carbonyl substituent group can also be by the substituent groups containing heteroaromatic, and amino acid, halogen containing sulfydryl take Generation.
2. the synthetic method of compound of formula I
By X and 2,2- dimethylthiazoles alkane occurs necleophilic reaction and is made.X can be C1-C6Straight chain and branch unsaturation alkane Chloro thing, bromo-derivative, sulfuric ester, sulphonic acid ester or the benzyl of base and the chloro thing of substituted benzyl, bromo-derivative, sulfuric ester, Sulphonic acid ester, preferably pi-allyl, isopentene group, but-2-ene base, benzyl, the chloro thing to methylbenzyl, bromo-derivative, sulfuric ester and Sulphonic acid ester can also be C1-C6Straight chain and branch carbonyls such as acyl chlorides, acylbromide, acid anhydrides, ester and carboxylic acid, the wherein carbonylation Closing object can also be further by the substituent group containing heteroaromatic, the amino acid containing sulfydryl, halogen substitution.
3. the pharmaceutically acceptable salt of compound of formula I falls within the scope of the present invention, pharmaceutically acceptable salt is Hydrochloride, sulfate, tartrate or citrate.
4. it is another object of the present invention to disclose compound of formula I in protection hematopoiesis, immune system and radiation protection In purposes.
The compound of the present invention can be prepared according to following scheme
X is Br, Cl ,-OSO3H、-SO2OR
Biological activity test
